Supposed that you met someone who can confidently convince you with scientific evidence that s/he knows how to neutralise the injection how much would you be willing to pay for the "antidote"?
Free market; there is no bidding cap.
**Twist: **there is no 100% guarantee that this will work; you are part of the experimental antidote trial. As with every trial there may be unspecified side-effects. You stilll get to keep your passport though (until next booster where the process repeats).
PS: I know NO ONE in here got the injection so ask others around for an opinion or simply theorise on what someone else would be willing to pay.
Please do not spoil the thought experiment.
Probably, at a maximum, similar to cost of college education. Similar expected benefit to long term outcomes.
